Please share your performance of the replacement battery as sold by iFixit (I'm interested in the New one, not B-Stock) as compared to the original battery from Apple for Macbook Air 13" mid-2011 (particularly, an i7 processor modification)?
Does it wear out faster? How long does it hold after 1 year+ of frequent (or, ideally, heavy) use? How many charge cycles does the iFixit version have, according to specs?
Update: I already contacted iFixit sales, but their answers were not satisfactory.
